d2a473a7b7 dsdb: Allow password history and password changes without an NT hash
We now allow this to be via the ENCTYPE_AES256_CTS_HMAC_SHA1_96 hash instead
which allows us to decouple Samba from the unsalted NT hash for
organisations that are willing to take this step (for user accounts).

(History checking is limited to the last three passwords only, as
ntPwdHistory is limited to NT hash values, and the PrimaryKerberosCtr4
package only stores three sets of keys.)

Since we don't store a salt per-key, but only a single salt, the check
will fail for a previous password if the account was renamed prior to a
newer password being set.

3b2a9083f8 lib:util:loadparm - fix leak in lpcfg_dump_a_parameter
This function calls talloc_strdup() for the parm_name passed into
it so that we can check whether it's a parametric entry. It's
allocated under the loadparm context passed into the function.
Primary consumer of this is "testparm" and so context short-lived in
typical use-case, but this is also exposed via pyparam and so the
loadparm context may be somewhat longer-lived depending on how it is
being used.
